To all whom it may concern:

Be it known that l, EDWARD BOWMAN, {L citizen of the United States. residing at ubuque. in the county of Dubuque and State of Iowa, have invented a certain new and useful Improvement in Adjustable Ventilator-Hoods for Automobiles, of which the following is a specification.

This invention relates to hoods winter use over the radiator fronts of automobiles to udjustably regulate the amount of cold air admitted. The object of the invention is to provide a mechanism. of this class which is readily applicable to and removable from position and which contains doors or shutters adjustable from the seat of the automobile to control the sine t mitted to the engine. This so" desirable because of the wel that us the engine heats up it will stand a great deal mo when it is COl( at starting, on ously inconvenient for the automobile to get out of his seat, the rain and mud, to go to the front 0 car to vary the hood opening as fore been necessary.

The invention consists in mechanism for carrying out the foregoing objects, which can be easily and cheaply made, which neat and compact in form. satisfactory in operation, and is not readily liable to get out of order. More pcrticulirly, the invention consists in many features and details of construction hereinafter more fully set forth in the specification and claims.

Referring to the drawings in which like numerals represent similar parts throughout the several views,

Fig. 1 is a perspective View of a metallic frame and operating parts connected therewith, upon which the imperiorate cloth forming a hood proper is built to make the complete device of this invention.

Fig. 2 is a front elevation of the radiator of on automobile of well known construo tion having a hood of this invention applied thereto the doors or slats being shown in closed position.

Fig. 3 is :1 side elevation taken from the right hand side of Fig. 2 showing a rope operating mechanism leading away to the automobile seat, the air doors or slats being arranged for simultaneous operation.

Fig. 4 is the same view as Fig. 3 but with certain mechanism in changed position so Specification of Letters Za tent.

that 0111 one of the doors is operated by the mechanism, said door being shown in open position.

"lg. 5 is a sectional detail view through the center of the hood of Fig. 3, removed from the automobile, the

Fig. 6 is a perspective view of the inside of the hood removed from the automobile, the ill doors being in the position of Fig. 5.

F 1g. 7 is a plan view of the front of the automobile showing the method of securing the hood of this invention thereto.

Fig. 8 is it side view 01 on alternative operating mechanism in which a push and pull lever is used instead of the rope of Figs. 3 and V In constructing the mechanism of this nvention a metallic frame of the type shown ill perspective in Fig. l is provided comprising top and bottom members 10, end members l2, and such' intervening members 14 p rullcl to members '10 us may be required to lcove the desired air passage openings 16 in the frame. The purticulnr frume here shown provided with two such openings and therefore has only one such dividing member 14. On the side members 12 near the top of each opening 16 is provided some sort oi a pivot bearing 18, the same in the particular case here illustrated taking the former circular eyelets through which the wire door frames 20 and 22 respectively pass and take pivotal bearings. These two door frames 20 and 22 are of U-shaped form conforming in general to three sides of the opening 16, heretofore referred to, and one extremity of each of these members 20 and 22 is provided with a short shaft end 24 adapted to pass through an adjacent eyelet 18, as shown. These members 20 and 22 or mode of spring material so that. by compressing the free arm carrying this short member a given doc frame may be disengaged from the adjacent bearing or eyelet 18 for the purpose of being slipped into a. pocket -formed in the covering material which makes the trains into a complete door, as more fully appears hereafter.

The opposite end of each end door frame member 20 and 22 has extending from it beyond the adjacent bearing 18 2, horizontal shaft 26, each inclosed with a. spring 27 arranged to tend to holdthe adjacent door closed. From each shaft extends a crank arm 28. These crank arms are in fact idenair doors both be-' reciprocatable bar 32, cotter pin 34]: holding the parts together. If it is desired to operate lower door 16 only while the upperdoor is closed this may be accomplished by merely removing cotter pinv 34 and then removing 'crankp1n 29' from bar 32. On the other hand the construction now to be described makes it possible to leave lower door 16 closed while the upper door is operated. The construction is Crank arm 30 is provided with crank pin 36 which extends into an elongated slot 38 in the bar 32. Pivoted to the bar 32, below slot 38, by any, suitable means as onstud 40 is a latch member 42 provided with a notch 44, the whole so arranged that when the parts are in position of Fig. 4 the bar 32 can reciprocate up and down past crank pin 36 without affecting crank arm 30 and its attached mechanism. 22; but on the other hand, when latch 42 is swung to the position of Fig. 1, the crank arm 36 is rigidly attached .to the bar and movement of the bar moves the crank arms 28 and 30 and consequently the members 20 and 22 in unison between the ositions of Figs. 3 and 5.

'avin provided the mechanisr: thus far describe the frame 10-12-44 is covered with suitable cloth material, such as a combination offelt 4:6'on the inside and oil-cloth 48 on the outside, attached thereto by suitable. means such as stitching 50, the same arranged so as to leave the perforations '16 clear and open and to provide suitably shaped and arranged rearwardly extending side walls 52, horizontal top wall 5i, adapted to embrace respectively the sides and top or the radiator front. and be detachably secured thereto by inwardly turned metallic clips 56, bent as shown in Fig. 7. The imperiorate hood material thus described is also made to form a bottom flap 58, detachably securable around the underside of the radiator by corresponding metallic clips 60. The hood top member 54: is provided with a perforation 62 arranged to allow the device to slip over the radiator cap 68 of conventional construction.

Stitched across the hood cover device just described in the lines 64 and 66 above the.

openings 16 are cover members for the door frames 20 and 22, the same being made in I theform of pockets corristi oi? outside members 68 connected with inside members 70. These pocket shaped door covers {iii- 70 are arranged ,to inclose and cover the wire door frames 20 and 22 described, the inside members 70 being of such a length and terminating in the line 72 so when either aasmea The device of this invention in the form shown in Figs. 5 and 6 is sold as an article of commerce, applicable to any automobile (the sizes'and shapes of course being varied to conform to the sizes of different makes of automobiles). The operator on purchasing the device applies it to the radiatcr end of the automobile usin, the clips 56 and 60 to attach it in place. aving done this, in one form of construction he attaches the pulley 74 to the automobile frame 75 and passes over it a rope 76 attached at one end 7 8 to the rod 32, the other end'80 leading away to the seat occupied by the driver of the automobile. In the alternative construction he mounts on the frame 75 of the automobile a pivot mechanism 82 for any suitable lever mechanism 84 attached to the rod 32 by suitable link connection 86 and connected by a push and pull rod 88 to the seat not shown of the automobile.

, Under this latter construction the operator seated in the automobile pushes or pulls the rod 88 to open and close the air door mechanisms of the hood of this invention. In the construction of Fig. 3 the operator pulls on rope to open the doors and allows them to close by gravity due to the weight of the Wire frames 20 or 22 and the coveringvpockets 68-70 with or without the assistance of springs 27.

In very cold weather the operator moves latch 42 to the posit-ion of Fig. 4 and manipulates only one of the doors. In warmer weather he puts the latch in the position of Figs. 1 and 3 and manipulates both dc rs.

construction By regulating the distance he moves lever and thus has entire control of the amount of air admitted to the radiator.

Having thus described my invention what I claim as new and desire to secure by Letters Patent, is:

1. In mechanism of the class described, in combination with an automobile having a radiator intake requiring regulation, a hood of flexible iz'nperfora'te material. detachably securable over the radiator, a plurality of air intake doors in said hood made of the same material as the hood and connected directly thereto movable between two positions to exclude and admit air to the automobile radiator, means operatable by the automobile driver on the seat for manipulating said doors in the ventilator hood, and means for selectively varying the number of doors ma nipulated by said operating means.
